The cold-formed forming machine is a multi-stage forming roll arranged in sequence, which exerts pressure on the sheet metal, strip or pipe at room temperature to produce plastic deformation, thereby obtaining plastic processing machinery and equipment for specific cross-section materials. It has the advantages of high material utilization, high production efficiency, high product accuracy, and low energy consumption. Roller cold bending forming machine is the main and most common type. Its working principle is to gradually bend the metal strip laterally with the help of a series of specific rolls. It is suitable for large-scale production with high product accuracy and stable quality. The structural composition of the roll-type cold-formed forming machine includes an uncoiler, which is responsible for unfolding the metal coil and feeding the production; a leveling machine, which eliminates the unevenness and internal stress of the sheet and guarantees the forming quality; the forming host, as the core, forms the material through the roll; a cutting device, which cuts off the steel according to the required length; a control system, which accurately regulates each part to ensure the normal operation of the equipment and stable product quality. In addition to standard roller forming machines, there are also special production lines designed for specific products, including C-shaped steel/Z-shaped steel forming machines, steel bearing plate (floor bearing plate) production lines, guardrail plate forming machines, photovoltaic bracket forming machines, cable tray forming machines, storage shelf forming machines, corrugated pipe forming machines, automobile girder/profile forming machines, roof panel/wall panel forming machines, etc. The development of cold-formed forming technology is roughly divided into three stages.In recent years, new cold-formed forming processes such as four-roll forming, flexible cold-formed forming, CAT forming, and “roll-punching” hole processing have emerged. [17] At the same time, in order to improve the accuracy and automation level, intelligent functions such as high-precision cold forming machines, eccentric adjustment gap mechanisms, servo motor cutting, remote operation and maintenance, and automatic conversion of CAD drawings have appeared. China has issued relevant industry and national standards, such as JB/T 11352-2013 "General Technical Conditions for Roll-type Cold-rolled (Bending) Forming Machinery" and GB/T 34385-2017 "General Technical Conditions for Roll-type Cold-formed Forming Machinery", marking the standardized development of the industry.
